“…A high BMI is reported to be a risk factor and to contribute to the severity of HS [2,17,18]. The lack of relationship between BMI and HS is similar to the studies from Ghana and Singapore [8,14].…”

“…The prevalence of HS in this population study was 2.2% with a 95% CI of 1.4-3.5%. This is higher than what was reported from other studies using the same validated questionnaire from Ghana, Australia, and Singapore, where a prevalence of 0.67% [8,13] and 0.59% [14] were reported. However, the prevalence in Nigeria is similar to what was reported in Denmark (2%) [5,7,14].…”

Background: Epidemiologic hidradenitis suppurativa (HS) studies from Africa are lacking. This study aimed at uncovering the prevalence of HS in Lagos, Nigeria, to validate an HS screening questionnaire, and to contribute to the Global Hidradenitis Suppurativa Atlas (GHiSA). Methods: This was a cross-sectional study of 802 healthy adults accompanying their relations to the outpatient clinic of Family Medicine and Ophthalmology at the Lagos State University Teaching Hospital in Lagos, Nigeria, following ethical approval. Verbal and written consents were obtained prior to inclusion of study participants. The study was conducted using a validated screening questionnaire. Screen-positive and randomly selected screen-negative participants were clinically examined. Severity was categorized using the Hurley score. Results: The prevalence of HS in the sample was 2.2% (18/802; 95% CI: 1.4–3.5%) with no gender predominance. The mean age in the HS group was 34 years (IQR 28–42) and the median body mass index (BMI) of the HS patients was 27.0 (IQR 21.4–28.6). There was no significant difference in BMI between the HS and control group. The screening questionnaire had a sensitivity of 1 (18/18), specificity of 0.8 (20/25), positive predictive value of 0.8 (18/23), and a negative predictive value of 1 (20/20). The axilla was the predominant site of affection (66.7%), and all HS patients were classified as mild disease (Hurley score 1). Conclusion: The prevalence of HS in Lagos, Nigeria, was 2.2% and, in this population, BMI did not appear to be a risk factor. The axilla was the most affected site, and all patients had a mild disease severity (Hurley score 1). Finally, the HS screening questionnaire is a suitable tool in population surveys.

“…The understanding of race-specific prevalence of HS is currently limited. US registry data have suggested that HS may be more common in the Black population than in Caucasians, while studies in Africa have suggested comparable prevalence rates to those previously found in predominantly white Australian population samples (8,9). Burden of disease and participation in pharmacological studies also appear to be unevenly distributed between the various races (10,11).…”

“…Among 26 people who screened positive on the questionnaire, only 10 (38%) were confirmed to have HS upon examination by a dermatologist. Accordingly, the questionnaire‐based prevalence of 1·7% was reduced to 0·7% after verification 6 . Similarly, questionnaire‐based prevalence of 0·8% in an Australian general population was reduced to 0·4% after verification 7 .…”
